The new coronavirus can be killed by using 84 disinfectant, and can be killed by using alcohol and chlorine disinfectant. Generally, 1:200 of 84 disinfectant can be used to wipe cell phones or office appliances, door handles, floors, etc. 84 disinfectant contains sodium hypochlorite, which produces hypochlorous acid in a water-solvent environment, and hypochlorous acid releases oxygen, which can oxidize viral nucleic acids. Experts introduce chlorinated disinfectant and 75% alcohol will destroy the membrane capsule of the new coronavirus. When using 84 disinfectant, be careful to wear a mask, rubber gloves, sunglasses if possible, and use it in a well-ventilated environment, lest the concentration be too high to the respiratory mucosa and cause coughing or itching, which is a disadvantage when using 84 disinfectant, and be careful to prevent new respiratory illnesses from arising.
